U.S.- Germany Cooperative Research: Process Chains for the Replication of Complex Optical Components: High Resolution Surface Zone Analysis

该奖项支持Don Lucca和俄克拉荷马州立大学的学生与德国亚琛和不来梅大学的广泛合作。该项目将专注于发现产生高科技新浪潮的因素，由此产生的美德跨区域合作研究中心涉及16个技术项目，重点是开发用于下一代信息技术和电信、医疗保健、生命科学、传感、照明和能源转换等应用的复杂、高质量光学元件的制造工艺。在设计、涂料、复制技术和测量科学和技术领域有技术项目。这个长期研究中心的资金，除了这里描述的项目外，主要是由德国国家科学基金会（NSF）的德国同行——德国研究基金会（Deutsche Forschungsgemeinschaft）提供的。美国项目“高分辨率表面区域分析”的研究重点是研究溶胶-凝胶衍生的金刚石可旋转硬模涂层的近表面机械性质，该涂层将用于超精密聚合物光学和玻璃的批量生产。利用纳米压痕技术研究硬质涂层的近表面力学性能，包括弹性模量和硬度，以及表面残余应力状态。深度剖面研究将在横截面和锥形截面涂层上进行，采用一种新开发的近表面区域分析方法。利用纳米刮擦技术研究模具涂层的粘附和分层行为。该项目还将进一步有助于开发先进的表面表征工具，以评估纳米尺度下的近表面机械状态。

0128050LuccaThis award supports Don Lucca and students from the Oklahoma State University in an extensive collaboration with the universities of Aachen and Bremen in Germany. The project will focus on discovering what factors are generating the new wave of high-tech The resulting U.S.-Germany Transregional Collaborative Research Center involves sixteen technical projects centered on the development of processes for the manufacture of complex, high-quality optical components for next generation applications in information technology and telecommunications, health care, the life sciences, sensing, lighting, and energy conversion. There are technical projects in the areas of deign, had coatings, replication techniques, and measurement science and technology. Funding for this long-term research center, with the exception of the project here described, is being supplied mainly by the Deutsche Forschungsgemeinschaft, the German counterpart to NSF. The research focus of the U.S. project, "High Resolution Surface Zone Analysis," is the investigation of the near-surface mechanical nature of sol-gel derived diamond-turnable, hard mold coatings which will be used in the volume production of ultraprecision optics of polymers and glasses. Nanoindentation will e used to study the near-surface mechanical properties including elastic modulus and hardness, and the surface residual stress state of the hard coatings. Depth profiling studies will e performed on cross-sectioned and taper-sectioned coatings with a newly developed method for near surface zone analysis. The adhesion and delamination behavior of the mold coatings will be explored with the use of nanoscratching. The project will also further contribute to the development of advanced surface characterization tools needed for assessing the near-surface mechanical state at the nanometer scale.
